Abstract
It is shown that noise emission from an engineering structure can be r educed by changing the spatial scale of the vibration field on the emi tting surface: with an ordered system of lightweight passive vibrators -radiators arranged on the surface and excited by its vibrations. The noise-reduction efficiency of the method is estimated considering the transfer characteristics of real vibrators.
